CROSS-REFERENCE TO RELATED APPLICATION

This application claims priority to a provisional patent application Ser. No. 60/572,326 titled, “Portable Bar-B-Q Platform,” filed May 19, 2004. The entire disclosure of Ser. No. 60/572,326 is incorporated by reference in its entirety.

FIELD OF INVENTION

The present invention generally relates to portable platforms and particularly to a portable platform configured for barbeque (BBQ) applications.

BACKGROUND ART

There exist in the art several types of decks and even portable and/or collapsible deck-like structures. Unfortunately, these structures are either too bulky or too large for specific seasonal uses such as food grilling or power tool use. Examples of collapsible structures are shown in U.S. Pat. No. 3,808,787 to Greenwood, U.S. Pat. No. 4,747,243 to Anstead and Patent Application 2003/0167701 to Rich that include structures such as porches. Other proposals require the removal of parts such as legs or rails to allow for the collapse of the structure. U.S. Pat. No. 4,691,484 to Wilson includes a portable deck that has a fixedly assembled wooden platform with parts secured by bolts.

U.S. Pat. Nos. 5,822,930 and 5,784,837 to Klein disclose a portable deck structure that employs the use of wheels for transport. The patent includes various ways to collapse the structure including a vertically collapsed position. In one embodiment of this invention there is a fold out feature that doesn't provide for the removal of parts.

Nevertheless, there are deficiencies in the prior art in that often the collapsible parts must be removed or are too bulky for portability and storage such as winter storage in a garage.

SUMMARY OF INVENTION

An important aspect of the present invention is the provision of a deck that creates a sturdy secure environment under and around devices such as barbeque grills and accessories, power tools and recreational equipment. The present invention can include several additional features for organizing accessory items on the deck.

Specifically, the present invention provides a portable collapsible platform for use with items such as barbeque (BBQ) grills that may include wheels to facilitate transport and may also include storage aids for accessories, for example, shelves and hooks. The present invention may also provide features such as utensil hangers, apron hangers, shelves, posts, deck space, grill area and a sturdy yet transportable base. In one embodiment, wheels are added to make the unit portable and storable. The invention provides a streamlined design in that the rails and shelves can be collapsed without having to remove them from the structure.

A related aspect of the invention is the provision of a structure that can be folded together with the side rails leafed or nested together into a compact configuration for storage or transport.

A further related aspect is an assembly that includes appropriate hinges and cooperating pivotable support braces to achieve the objectives of the invention.

Briefly, the invention provides a portable deck adapted for outdoor use that includes a base structure forming a floor. A retaining rail is attached by hinges to a side of the base structure, the side rail being pivotable from and upright position to a collapsed position folded toward the deck floor. In the use position, each rail extends upwardly from the side or rear edge of the deck and is supported by means such as a retaining device attached to the perimeter of the deck or, alternatively, foldable brace members positioned between the rails and the deck floor. In the storage position, each rail is collapsed into a position folded toward the floor. In a preferred embodiment, one retaining rail is attached by hinges to an end of the base structure, and a second retaining rail, also pivotable between a use position extending upwardly from a side of the deck is similarly pivotable between an upright use position and a storage position wherein it is collapsed into a position folded toward the floor.

The deck may be supported on a plurality of removable or extendable-retractable wheels. A foldably supported shelf may be pivotally attached to the top of at least one of the rails.

In one embodiment, brace members with pivoting central joints are angularly disposed between the deck floor and a post that forms each rail assembly to support it in an upright position. Similar pivoting brace members are positioned between one or more posts and each shelf to hold it in a level position.

In an alternate embodiment, a removable rod is used in combination with cooperating retaining loops in the form of brackets attached to the deck perimeter and provided with an aperture sized to receive the removable rod to thereby lock each rail assembly in its upright position.

DETAILED DESCRIPTION

Referring now to the drawing figures, FIG. 1 shows the deck assembly of the present invention generally at 20. A deck floor 28 is integrally formed with base 22 which forms a lower perimeter supporting deck floor 28. Base 22 can be constructed of structural lumber, or constructed using materials known in the art, such as plywood, recycled plastics or composites. Base 22 includes a pair of end face member 25 and a pair of side face members 23. Preferably the structure includes a framework of a beam 24 and cross-members 26 as shown in FIGS. 4 and 7. Alternatively, as shown in FIG. 7, several lengthwise beams 27 can be used. Members 24 and 26 may be of an interfitting configuration, for example, as illustrated as 24A and 26A in FIGS. 8 and 9.

Deck floor 28 provides a surface to support users and such items as grills, tools and recreational equipment. Floor surface 28 may be plywood or other sturdy materials and may be treated with flame retardants to reduce the risk of fires as well as preservatives to prolong the useful life of the structure. An end rail 16 and a side rail 18 are hingedly attached to an end and a side of deck floor 28, respectively. As shown, side rail 18 is preferably of a length less than the full length of the deck assembly in order to allow for easy access to the deck surface and for purposes of allowing adequate clearance around grill 14 as best seen in FIG. 3.

Useful features to increase the functionality, efficiency, and enjoyment of deck assembly 20 may include at least one side shelf 30, and preferably also an end shelf 31 supported by posts 32 and angled braces 36. The portability and ease of storage of deck assembly 20 is enhanced by making shelves 30 and 31 foldable and collapsible. This may be accomplished through the use of post hinges 34 and shelf hinges 35 to hingedly attach shelves 30 and 31 to posts 32. To retain the level position of shelves 30 and 31 relative to vertical posts 32, lockable and foldable brace support members 36 are added as illustrated in FIG. 1. Hinges 34 and 35 may be of conventional design of the type used on various doors and thus are not illustrated in detail. Other devices known in the art are also possible within the scope of this invention to provide a lockable means to hold shelves 30 and 31 and posts 32 in place while allowing them to be released to fold toward floor 28 for storage or transport.

To increase the transportability of platform 20, the present invention further provides wheels 38 that may be slidably attached to a track (not shown) that has means such as a thumb screw to lock the wheel in a retracted position for use of deck assembly 20 in a stationary position and an extended position, for rolling transport of assembly 20. Arrows 44 generally illustrate extension and retraction of the wheels 38. As seen in FIGS. 2, 2A and 2B, the wheels 38 and be attached to a yoke 45 which is pivotable about shafts 47. A lever 43 can be provided on each end of the shafts 47 for manual rotation of the shafts. By use of eccentric placement of the yokes 45 and springs 49, the wheels 38 are locked in a retracted position as shown in FIG. 2B when the deck 20 is placed in a stationary position for use.

Alternatively, as shown in FIG. 10, the wheels may be in the form of casters having supporting shafts 40 that are each received in a socket 50 when used and removed when the deck assembly is placed in a stationary use position. Such wheels and casters are sized and selected taking into account the size and weight of the particular deck assembly. The wheels 38 may be lowered, installed or removed by raising the deck, if necessary, either by manually lifting or by use of levers or a hydraulic jack, etc., as needed. In addition to the illustrate designs for making wheels 38 extendable and retractable, other designs will be apparent to those skilled in the art.

An alternative, preferred embodiment showing a different scheme for supporting the end and side rails 16 and 18 in their upright use positions is shown in FIG. 11. In this embodiment the lower braces 36 are eliminated. Instead, brackets 60 are attached to an end perimeter face member 25 and side perimeter face member 23. Circular shaped apertures 62 are provided in each bracket 60 in alignment with each other. A rod or pole 64 of appropriate length and diameter is inserted through the aligned apertures 62, as illustrated, with the posts 32 in their vertical orientation, thereby entrapping the posts 32. As in the case of the earlier described embodiment, posts 32 are pivotally attached to deck surface 28 by means of hinges 34. The rods 64 are retained in position by cotter keys or pins 66 or other known types of mechanical fasteners.

While the invention has been described in conjunction with specific embodiments, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art in light of the foregoing description.
